Mailgun

About Mailgun

Mailgun provides an email API and SMTP relay for application messaging. Start with an authenticated test domain and a small application message, then inspect the events recorded as it is sent. This is useful when developers need to tell a temporary delivery delay from a permanent failure. Make sure your application handles callbacks or repeated send attempts carefully before moving account or billing messages to the service. Check region, retention and plan limits for the setup you intend to use. Test domain records and one failure case before making Mailgun part of a workflow customers depend on.
